The Timney HK MP5 trigger is factory set with a 900 g first stage and a 900 g second stage, elevating the platform and allowing the shooter to achieve the highest level of accuracy.
All trigger components are expertly designed and precision‑machined from premium materials to ensure a lifetime of reliable performance. The trigger housing is manufactured from 6061‑T6 aluminum and black anodized to provide excellent resistance to weather and corrosion. The hammer is made from S7 tool steel, heat treated, and NP3 coated to deliver maximum lubricity throughout the trigger pull. Both the trigger shoe and the disconnector are machined from A2 tool steel, heat treated, and carbonitrided to ensure a smooth and consistent trigger feel.
Timney’s two‑stage replacement trigger for HK MP5 semi‑automatic firearms utilizes the rifle’s original ejector lever, ejector spring, and ejector pin, which are matched to the chambering of your firearm.
Compatibility:
This trigger is compatible with HK 91, 93, and 94 models and their clones using SEF / semi‑auto trigger housings and corresponding safety levers.
It is NOT compatible with the SP5, Ambi/Navy/FBI trigger housings, or .22‑caliber clones, as these platforms use entirely different internal designs.
